Hi Folks, I need a schematic for this transistor curve tracer, I went on a site and just found the manual. eBay has one for $75.00 and if possible I would like to build one myself. Does anyone have a schematic and parts list ?

Thank you for the additional information and I do see the schematic and parts listed. A quick question regarding the transformer, it shows a ratio of 2:1. Also a part # for the xformer, any idea what manufacturer goes with part number.“T-1”

Tony,

Save the trouble - build the Octopus as outlined in the 1950's era Electronics Installation and Maintenance Bulletin (NAVY):

Seems every shop had one until the Huntron Trackers came about. I built my first one as a teen, from a photocopy of the same schematic. One 6.3V filament transformer, three resistors (560 ohms, 1K ohms, and 100 ohms), a power switch, and a DPDT switch if you want to use an audio oscillator instead of 60Hz.
